CARRIAGE-AXLE LU BRICATOR.

SPECIFICATION forming part of Letters Patent No. 514,905, dated February 20, 1894.

Application filed May 29,1893.

To all whom it may concern.-

Be it known that I, FENELON B. BROOK, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Carriage-Axle Lubricators and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to axle lubricators.

The objects of the improvements are to provide a wheel axle which shall be clean and free from grit, which shall require oiling only at long intervals, and which shall reduce to a the revolving hub.

Figure 1 represents a perspective vlew of a wagon axle to which my improvements have section of the same. Fig. 3 is a detail transverse section of the axle. Fig. 4 is a transverse section of a modification of the inven- Fig. 5 is a detail perspective view of still another modification.

A represents the axle.

B is a longitudinal groove cut in the axle along its upper side.

O is a strip or pad of absorbent felt placed in and fitting the groove B.

b, Fig. 4, is a supplementary channel running along the bottom of groove B and communicating with it.

D are holes through the felt 0, through which the lubricating oil is applied.

The oil passes into and along the cavity a or channel 19, and is absorbed by the felt strip O, and fed to the wheel hub, as needed by capillary attraction, just as a lamp wick feeds oil. In this way the axle is at all times kept thoroughly lubricated and needs attention only about once a month.

When the vehicle is in motion the vibra tion of the axle throws the oil up from channel or cavity against the felt pad and is abfierial No. 476,304. (No model.)

sorbed thereby. When the carriage is not in motion the oil stays quietly in the channel. Theooil is fed only when needed. As the wheel is required to be taken 0% onlyat long intervals the axle is kept clean and free from grit. As the axle does not revolve the groove and pad are always at the top of -the axle, where no weight of the. load or strain is exerted, and where any loose play serves to aid the lubrication of the axle.

The groove B may extend any length required along the axle up onto the inner collar if desired.

In Figs. 1, 2 and 3 the supplementary channel b is dispensed with, and a longitudinal cavity a. made on the bottom side of the pad 0 for holding the supply of oil.

In Fig. 4:, the channel b and cavity a. may or may not be employed. The pad O" hasa lengthwise groove e out into its upper side, which groove serves to catch and retain any glaze, foreign matter, or residuum during the rotation of the hub.

The invention may be applied to all existing carriages as well as new ones, by removing the wheels and applying a reciprocating tool to the axle for the purpose of channeling out the necessary grooves. This machine is slipped over and clamped to the axle during the operation. Afterward the pad is put in place and the lubricatoris complete and ready for use.

I claim- 1. An axle having a groove formed longitudinally therein, and a strip of absorbent material in said groove provided with a longitudinal channel and a series of holes through which oil is applied.

2. An axle having a longitudinal groove therein, and a strip of absorbent material placed in' said groove, said material having a longitudinal channel therein.

In testimony whereof I affix my signature in presence of two witnesses. I I FENELON B. BROOK. Witnesses:

Gno. L. CLARK, GEO. W. BROWN.
